Application iled April 211,l 1913. Y Serial No. 763,296.

To all whom t may concern.' i

Be it known that I, BROR E. ANGLUND, a citizen of the United States,residing at Atwater, in the count-y of Kandiyohi and State of Minnesota,have invented certain new and useful Improvements in Cream-Coolers, ofwhich the following is a specification.

My invention relates to an improvement in cream coolers and has for itsobject to provide a device of this character which shall be simple andinexpensive in construction and eliicient and sanitary as a coolingdevice.

My device comprises a can with a casing containing an air chambersecured to the can near its top. The casing acts as a float and is ofsuch size and so positioned that when the can is filled with cream andplaced in water it will be held upright with the top of the can onlyexposed.

The cover for the can is of peculiar construction and is provided withwide ventilating slots which permit the air to circulate freely throughthe can. The cover is also provided with a filter which allows thecirculating air to pass into and out of the can but prevents theentrance of dirt, dust, etc.

The full objects and advantages of my invention will appear inconnection with the. detailed description thereof and are particularlypointed out in the claims.

In the drawings, illustrating the application of my invention in oneform,-Figure 1 is a side elevation of my invention. Fig. 2 is asectional side elevation. Fig. 3 is a side elevation of the cover withits front walls partly broken away to show its construction in detail.

The cream cooler of my invention comprises an elongated can 10 ofrelatively small cross sectional area. To the can 10 near its top issecured a float or casing 11. The casing 11 is provided with an airchamber 12 of such size and so positioned that when the can is filledwith cream and placed in water the casing holds the can.Y upright withthe top only exposed. Attached to the top of casing 11 are brackets 13for the purpose of securing handle 14 to the can. A cover 15 is providedhaving a handle 16 fastened to its top plate 17. Around the outer edgeof top piece 17 is a downwardly inclined ange 18. Attached to the bottomof top plate 17 is a collar 19 adapted to fit into the top of can 10.Collar 19 is pro- Spe'cificaton of Letters Patent.

Patented not?. a, isis.

vided with wide lslots 20 cut into its periphery adjacent the top piece17, and with an annular projection 21 formed beneath the slots 2O toprevent vthe cover 15 from being pushed down over the said slots.Removably positionedwithin the collar 19 is a ring 22 `provided with ahandle 23. Stretching across the top of ring 22 and f engaging betweenthe said rin 22 and the C b b collar 19 is a lter 24 made of cloth orother suitable material for the purpose of permitting the freecirculation of the air while prevent-ing the entrance of dirt. Ring 22is held lirmly positioned in collar 19 by means of springs 25 formed inthe wall of collar 19, each of said springs 25 being formed by cuttingtwo longitudinal slots in the collar 19 a short distance apart andforcing the material between the slots t0- ward the center of thecollar. At the bottom of can 10 is a flange 26 provided with notches 27cut therein to permit the escape of the air when can 10 is lowered int-othe water.

In operation the cream cooler of my invention would be filled with creamnearly to its top, a clean filter would be spread over the ring 22 andinserted into the collar 19 and the cover 15 would be placed on can 10.The said can 10 would then be lowered into the water, slots 27permitting the escape of the air from the bottom flange 26 of the can.@wing to its weight the can 10 would sink into the water until itreached a point where it would be held upright in the water with the toponly exposed by the float or air chamber 12. This construction permitsvery rapid cooling of the cream, and the constant circulation of pureair within the can serves to keep it sweet for a much longer time thanmight be otherwise possible.

This cream cooler solves one of the problems that confronts the creamindustry of today. It provides a simple and inexpensive method ofkeeping cream sweet and cool for a long period of time.

It should be understood that my invention is not limited to the coolingof cream alone, but may be used also for milk or any other fluid whereeflicient, economical and sanitary cooling is desired.

I claim 1. A cream cooler having a detachable cover comprising a toppiece with a downwardly sloping outer edge, a collar adapted to registerwith the opening in the can and having Wide slots in its peripheryadjacent its points of attachment to the top piece, a flange belonT theslots to register with the top Wall yof the can, and means removablyattached Within the collar tovpermit the circulation of air Vin thereceptacle While preventing the entrance of dirt.

2. A cream cooler comprising a top piece, a collar attached t0 thebottoni of said top piece and having Wide slots in its peripheryadjacent said top, piece7 a ring removably positioned Within saidcollar, a handle on said ring, and a lter inserted over the trance ofdirt.

In testimony vwhereof I aliix my signature in presence of tWo Witnesses.
